Pressurized Water Spray SystemsBesides its installation on car decks principally loading automobiles, the water spray systems can also be used for cooling the upper decks of LNG/LPG carriers with water spray, and for fire extinction of engine room and pump room. By discharging water in the form of fine fog, the water spray systems secures Excellent cooling and smothering effects on oil fires as well as ordinary fires.主に自動車を積載するカーデッキに設置するほか、LNG/LPG船の上甲板用散水冷却やエンジンルーム、ポンプ室などにも使用できます。噴霧状に散水することで、冷却・窒息効果に優れ、一般火災のほか、油火災にも有効です。Diagram Configuration of Water Spray SystemStart SignalPressure Switch Fresh WaterPressure Tank Pump StratingPanelPumpSea waterFresh WaterCompressed AirControl PanelActuation SignalSpray Head Electro-magneticValveSelection ValveLimit Switch Selection ValveOpen/Close SignalSystem Outline1. During the normal supervisory state, the pipings extending up to the valves are kept filled with pressurized water from the fresh water pressure tank.2. The area of fire occurred to be identified.3. The Selection valve for the affected area is opened.4. As the valve is opened, the pressure in the water tank falls, causing the pressure switch on the tank to actuate, this starts the pump motor, and water is discharged from the spray heads.1. 平常警戒時は、清水圧力タンクにより、圧力水が分配弁までの配管内に充満しています。2. 火災発生区画を確認します。3. 該当区画の分配弁を開放します。4. 開放によって、清水圧力タンクの圧力が低下し、圧力タンクの圧力スイッチが作動。ポンプモーターを起動して、スプレイヘッドから放水を開始します。NAMEMODELSPECIFICATIONSSPRAY NOZZLEMHF320B20L/min. at 0.35MPa SPRAY ANGLE:120°SPRAY NOZZLEMHF330A30L/min. at 0.35MPa SPRAY ANGLE:90°SPRAY NOZZLEMHF330B30L/min. at 0.35MPa SPRAY ANGLE:120°SPRAY NOZZLEMHF123A60L/min. at 0.35MPa SPRAY ANGLE:120°SPRAY NOZZLEMHF11460L/min. at 0.35MPa SPRAY ANGLE:120°SPRAY NOZZLEMHF12170L/min. at 0.35MPa SPRAY ANGLE:60°SPRAY NOZZLEMHFJ029105L/min. at 0.35MPa SPRAY ANGLE:120°品 名型 式仕 様水噴霧ノズルMHF320B20L/min., 0.35MPa 散水角度：120°水噴霧ノズルMHF330A30L/min., 0.35MPa 散水角度：90°水噴霧ノズルMHF330B30L/min., 0.35MPa 散水角度：120°水噴霧ノズルMHF123A60L/min., 0.35MPa 散水角度：120°水噴霧ノズルMHF11460L/min., 0.35MPa 散水角度：120°水噴霧ノズルMHF12170L/min., 0.35MPa 散水角度：60°水噴霧ノズルMHFJ029105L/min., 0.35MPa 散水角度：120°
